The Effect of Computer Animation in the Teaching of Chemistry at Higher Secondary level: An Experimental Study

Purpose - The purpose of this experimental study is to investigate the impact of teaching Oriental Music using Blended Learning (BL) approach for the students of senior secondary level in Sri Lanka specifically focusing on their achievement on required competencies of Oriental Music at Ordinary Level. The study analyzes the academic performance of students with detailed comparison of BL environment and traditional learning environment. Authors propose the application of BL approach to teach Oriental Music and study its impact on improvement of students’ competency. The study conducted with the application of a mixed instructional design model of objectivist and constructivist approaches for the design of the blended learning course in a student centred learning environment. Methodology - The study was directed by using true experimental study design with pretest and posttest control groups. BL was applied to the experimental group and the traditional instruction method was applied to control group. 9 schools from Colombo district were randomly selected for the experimental and control groups covering all the three existing school types of Sri Lanka. The study group consisted of 360 students of Grade 10 and Grade 11 who has been studying Oriental Music as a subject for General Certificate of Education Ordinary Level. To analyze the data Descriptive statistics, Paired samples t test, Independent samples t test were utilized. Findings - The findings of the experiment indicated that students who has studied Oriental Music under BL strategy showed a significant improvement in their music academic performances after the intervention. The mean post-test of the experimental group was 71.75 which is significantly higher than the mean control group which was 52.07. The mean difference was 19.68 1.91. Hence, there is a statistically significant increase in the performance of students who studied Oriental Music under blended learning. Thus, it is clearly evident that the blended instruction was effective. Significance - This study indicated a positive platform to mould and cater the entire teaching learning process by introducing BL strategy to Sri Lankan secondary education system and fulfilled an existing research gap by utilizing BL to teach highly traditional abstract art. Results of the study contributes to the curriculum designing field with novel ideas to adapt blended instructions to teach secondary level students effectively.

This experimental research is evaluated the significance of Yoga on Memory of Secondary School Students, aged between 13 and 17 years. Pretest-posttest of control and experimental groups are designed for this study. The total seventy students were included equally in both control and experimental groups. Before the experiment the researcher administered a pretest for measuring memory of the total seventy students which was measured through in terms of number of trials using Instructional Manual for Memory Drum ( Dr. Vivek Bhargava, Chairman, Harprasad Institute of Behavioural Studies, 41-12, Hardeep Enclave, Sikandra. AGRA(U.P.). And the same test was administered as post –test for both groups. The significance was measured through in terms of number of trials. To remove the difference statistically in the initial status of the two groups, the researcher analyzed the data with the statistical technique of Analysis of Covariance (ANCOVA). Thus both groups initial status had been equated. The main findings of the experimental study proved that the regular yoga practicing students develop the homeostasis of persons in a balanced manner. It helps to attain the complete self-realization. This study reveals that Yoga will assist to improve the students’ memory in a magnificent level. So, Yoga should be practiced for students in the schools of Kerala. Through yoga the students’ memory has increased.

Positive Effect

A quasi-experimental study was conducted to seewhether constructivist approach to science instructioncould promote perception of nature of science amongeighth grade students. Purposive sampling was employedto select the schools for the study. Perception of nature ofscience test was developed by the researcher and wasadministered before and after the treatment. Analysis ofCovariance test was performed to control the initialvariance. The results showed that Constructivist teachingis more effective than conventional teaching in terms ofperception of nature of Science among 8 standardstudents. It was also found that constructivist approachwas equally effective for both boys and girls in improvingachievement and attitude towards science. Aconstructivist environment was preferred to a traditionalclassroom by the students. The results confirm researchsupporting the positive effect of constructivist learningpractices and view that constructivist approach to teachscience is a viable alternative to traditional modes ofteaching.

Jigsaw Technique

This research paper is designed to set forth ideas on how to implement cooperative learning and examine its effect on social and cooperative skills while imparting science education at the Secondary Level. The strategy used is Jigsaw Technique making heterogeneous groups based on intelligence and gender. Instructional material and observation schedule were constructed by researchers. The cooperative skills of the students were found improving during the experimental period, and they developed positive interdependence, face-to-face interaction skills, and feeling of individual accountability, as compared by Mann WhitneyUtest. The students developed the feeling of working in a group in the classroom of science, and it also improved performance, as the discussion always leads to a considerable degree of clarity of concepts.

Illumination Mode

The tilted beam illumination method is used to improve the resolution comparing with the axial illumination mode. Using this advantage, a restoration method of several tilted beam images covering the full azimuthal range was proposed by Saxton, and experimentally examined. To make this technique more reliable it seems that some practical problems still remain. In this report the restoration was attempted and the problems were considered. In our study, four problems were pointed out for the experiment of the restoration. (1) Accurate beam tilt adjustment to fit the incident beam to the coma-free axis for the symmetrical beam tilting over the full azimuthal range. (2) Accurate measurements of the optical parameters which are necessary to design the restoration filter. Even if the spherical aberration coefficient Cs is known with accuracy and the axial astigmatism is sufficiently compensated, at least the defocus value must be measured. (3) Accurate alignment of the tilt-azimuth series images.
